This edition of the FAL Bulletin analyses the requirements of and the advantages offered by the Customs-Trade Partnership Against Terrorism (C-TPAT) of the United States and the Authorized Economic Operator (AEO) programme implemented by the European Union.Supply chain security, especially for foodstuffs, has grown considerably in importance in recent years, owing to a combination of different factors which are emerging or becoming more significant, making the requirement of ensuring that a cargo is harmless increasingly essential and valuable during trade negotiations.In the field of certifying the harmlessness of a cargo, a number of private-sector standards have arisen worldwide, but the benefits offered by the C-TPAT and AEO programmes are well above those of their private-sector counterparts.As a first step, a comparative analysis of the programmes implemented by the two largest markets in the northern hemisphere is needed in order to provide to Latin American and Caribbean exporters the information they need in order to modify or tailor their installations and production procedures, to achieve greater market entry.

Abstract Background Smallpox is a lethal disease that was endemic in many parts of the world until eradicated by massive immunization. Due to its lethality, there are serious concerns about its use as a bioweapon. Here we analyze publicly available microarray data to further understand survival of smallpox infected macaques, using systems biology approaches. Our goal is to improve the knowledge about the progression of this disease. Results We used KEGG pathways annotations to define groups of genes (or modules), and subsequently compared them to macaque survival times. This technique provided additional insights about the host response to this disease, such as increased expression of the cytokines and ECM receptors in the individuals with higher survival times. These results could indicate that these gene groups could influence an effective response from the host to smallpox. Conclusion Macaques with higher survival times clearly express some specific pathways previously unidentified using regular gene-by-gene approaches. Our work also shows how third party analysis of public datasets can be important to support new hypotheses to relevant biological problems.

Within the stone monumental artefacts artistic fountains are extremely favorable to formation of biofilms, giving rise to biodegradation processes related with physical-chemical and visual aspect alterations, because of their particular exposure conditions. Microbial diversity of five fountains (two from Spain and three from Italy) was investigated. It was observed an ample similarity between the biodiversity of monumental stones reported in literature and that one found in studied fountains. Mechanical procedures and toxic chemical products are usually employed to remove such phototrophic patinas. Alternative methods based on natural antifouling substances are recently experimented in the marine sector, due to their very low environmental impact and for the bio settlement prevention on partially immersed structures of ships. In the present work groups of antibiofouling agents (ABAs) were selected from literature for their ability to interfere, at molecular level, with the microbial communication system “quorum sensing”, inhibiting the initial phase of biofilm formation. The efficacy of some natural antibiofoulants agents (ABAs) with terrestrial (Capsaicine - CS, Cinnamaldehyde - CI) and marine origin (Zosteric Acid - ZA, poly-Alkyl Pyridinium Salts – pAPS and Ceramium botryocarpum extract - CBE), incorporated into two commercial coatings (Silres BS OH 100 - S and Wacker Silres BS 290 - W) commonly used in stone conservation procedures were evaluated. The formation of phototrophic biofilms in laboratory conditions (on Carrara marble specimens and Sierra Elvira stone) and on two monumental fountains (Tacca’s Fountain 2 - Florence, Italy and Fountain from Patio de la Lindaraja - Alhambra Palace, Granada, Spain) has been investigated in the presence or absence of these natural antifouling agents. The natural antibiofouling agents, at tested concentrations, demonstrated a certain inhibitory effect. The silane-siloxane based silicone coating (W) mixing with ABAs was more suitable with respect to ethyl silicate coating (S) and proved efficacy against biofilm formation only when incompletely cured. The laboratory results indicated a positive action in inhibiting the patina formation, especially for poly-alkyl pyridinium salts, zosteric acid and cinnamaldehyde, while on site tests revealed a good effect for zosteric acid.

Two new cyclohexenones (antheminones A and B) and a new cyclohexanone, (antheminone C) along with five known compounds were isolated from the leaves of Anthemis maritima L. The structures were mainly deduced from extensive 1D and 2D NMR spectroscopy and mass spectrometry. The new compounds were tested in vitro for their cytotoxic activity against adherent and non-adherent cancer cell lines. Antheminones A and C exhibited significant antiproliferative activity against leukemia cells with IC(50) values ranging from 3.2 to 14 microM.

An integrated instrument package for measuring and understanding the surface radiation budget of sea ice is presented, along with results from its first deployment. The setup simultaneously measures broadband fluxes of upwelling and downwelling terrestrial and solar radiation (four components separately), spectral fluxes of incident and reflected solar radiation, and supporting data such as air temperature and humidity, surface temperature, and location (GPS), in addition to photographing the sky and observed surface during each measurement. The instruments are mounted on a small sled, allowing measurements of the radiation budget to be made at many locations in the study area to see the effect of small-scale surface processes on the large-scale radiation budget. Such observations have many applications, from calibration and validation of remote sensing products to improving our understanding of surface processes that affect atmosphere-snow-ice interactions and drive feedbacks, ultimately leading to the potential to improve climate modelling of ice-covered regions of the ocean. The photographs, spectral data, and other observations allow for improved analysis of the broadband data. An example of this is shown by using the observations made during a partly cloudy day, which show erratic variations due to passing clouds, and creating a careful estimate of what the radiation budget along the observed line would have been under uniform sky conditions, clear or overcast. Other data from the setup's first deployment, in June 2011 on fast ice near Point Barrow, Alaska, are also shown; these illustrate the rapid changes of the radiation budget during a cold period that led to refreezing and new snow well into the melt season.

En el marco de las discusiones en torno al "valor" en tiempos de posautonomía, se diagrama un mapa que articula los diversos modos en que los textos narrativos de los poetas Fabián Casas, Washington Cucurto y Juan Diego Incardona, reinventan, singularmente, el imaginario populista (nostalgia barrial desplazada al vacío representacional de la experiencia zen; religación ideológica y política del sujeto colectivo; discurso revolucionario en clave de farsa y banalidad), a la vez que definen, desde esas inflexiones, tres economías ficcionales como tres posiciones en relación con el trabajo como uno de los nudos de la cultura del nuevo capitalismo: ocio, artesanía, y superproducción. La película Historias extraordinarias de Mariano Llinás constituye otra versión del modelo artesanal y, desde su particular economía, un acontecimiento narrativo en la ficción argentina del presente

Entre 1956 y 1961 Severo Sarduy publicó una importante cantidad de textos sobre literatura, plástica y teatro cubano en el Diario Libre, Lunes de Revolución, Nueva Revista Cubana, Mañana libre y Combate 13 de Marzo. Participó de la explosión que caracterizó a la prensa literaria cubana a partir de la Revolución y se inscribió en las filas de los intelectuales que trabajaron en favor de ella. Entregado a sus labores de periodista plástico, un muy joven Sarduy entrevista al famoso pintor Mariano Rodríguez (1912-1990), co-fundador junto al escultor Alfredo Lozano (1913-1997) y a los escritores José Lezama Lima (1910-1976) y José Rodríguez Feo (1920-1993) de la revista Orígenes. Esta entrevista fue publicada en La Habana el 12 de octubre de 1959 y en ella se exponen juicios estéticos y políticos sobre el régimen de visibilidad cultural del arte cubano en el nuevo orden social. Cabe destacar que, a pesar de la ruptura que se produjo entre los editores de Orígenes, Mariano Rodríguez se convirtió en el creador del "Eolo" que sirvió de ícono a la postrera revista Ciclón (1955). Por lo tanto, presentamos un recorrido por dicha entrevista profundizando el breve pero significativo vínculo-desencuentro sucedido entre ambos
